Quite true, it certainly stops any more entropy (murder) from occurring, but
it doesn't increase extropy either. A more extropic thing to do, once an
involuntary irreversible entropic act (murder) has been committed, is finding
out why these people were murdered in the first place. By keeping these people
alive for study and possible rehabilitation, we increase our chances of
deterring murder at its source - weather it be bad genes, upbringing, economic
status, or what have you.
